What is Force?
The first law states
What is an object at motion tends to stay in motion and an object at rest stays at rest?
What is = acceleration is produced when a force acts on a object?
The third law states
What is for every action there is an equal and opposite re-action?
Born on
What is Dec. 25th 1643?
2 = forces act on an object
What is Balanced forces?
This law is also know as the Law of
What is Inertia?
Two components needed to know the acceleration of a object
What is Net Force and Mass of an object?
Give an example of the Third Law of Motion
What is answers may vary?
Walking? A bouncy ball? Swimming? Hitting a baseball?
Most famous discoveries was
What is gravity?
Unequal forces causing an object to move
What is Unbalanced forces?
Inertia tends to do
the formula to calculate this is
What is Force= Mass x Acceleration?
True or False; A rocket taking off follows Newton's 3rd Law. Explain
What is TRUE?
The rocket engine pushes hot exhaust gases downward which in response pushes the rocket upward with equal force.
Was know for
What is the 3 Law's of Motion?
Resistance from the surface of an object moves over another surface
What is Friction?
True or False; In order for an object to be following the 1st Law of Motion, the force applied to the object must be balanced.
What is TRUE?
An object at rest tends to stay at rest unless an outside unbalanced force applies!
Ture or False; Sally used her bike to pick up groceries from the store, it was easier for her to peddle home after picking up the groceries.
What is FALSE?
After adding mass to her bike it would take her more force to peddle the bike home.
Example why swimming follows the Third Law
What is the force of the hand going backward in the water causes a force in the water to move in the opposite direction?
What is a physicist and mathematician?
or
remain unchanged
What is Inertia?
Give two examples of different objects following the 1st Law of Motion. (one for rest) and (one for motion)
What is a book on a shelf and planets orbiting the sun?
An object with a mass of 55kg is observed to accelerate at the rate of 2m/s2. Calculate the total force required.
What is F = M x A
F= 55kg x 2m/s2
F= 110 N?
Earthquakes are in the category of the 3rd Law of Motion because
What is the plates create a tension of the unbalanced forces which cases the earth's surface to react by braking apart?
